If you own a Dell PC, you might want to be a bit more careful with installing the latest system updates. According to multiple reports on social media, there’s a new BIOS version that could end up wrecking Dell Latitude 5320 and 5520 laptops, the Inspiron 5680 desktop, and even the Alienware Aurora R8.

　　There are three specific BIOS versions that are causing issues. On the Dell Latitude 5320 and 5520, the BIOS number comes in at version 1.14.3. On the Dell Inspiron 5680, it comes in at version 2.8.0, and on the Alienware Aurora R8, it’s version 1.0.18. Based on social media accounts, after installing this BIOS version, users report that these systems are unable to boot into Windows. In some cases, users can’t even access their files and other important content.

　　Dell has yet to issue an official response on these problems, but according to Tom’s Hardware, the company is no longer offering these BIOS updates on its website. There are also some workarounds for restoring impacted PCs, including downgrading the BIOS. This involves downloading older BIOS on the problematic PC, and creating what’s known as a BIOS recovery tool. Dell offers step-by-step guides and instructional videos on its website, though it is for more experienced users.
